Ingredients Overview

The key ingredients in this High Protein Quiche are eggs, Greek yogurt or cottage cheese, vegetables, and lean protein like chicken, turkey, or smoked salmon. Eggs are the base of the quiche, providing structure, protein, and richness. Using fresh, high-quality eggs ensures a tender, fluffy interior and helps the quiche set properly.

Greek yogurt or cottage cheese adds extra protein and creaminess without the need for heavy cream, keeping the dish lighter and lower in fat. These dairy ingredients also contribute a slightly tangy flavor that balances the vegetables and herbs. For a dairy-free alternative, silken tofu or a plant-based yogurt can be used.

Vegetables like spinach, bell peppers, mushrooms, and onions provide fiber, vitamins, and minerals while adding flavor, color, and texture. They can be sautéed or roasted before being added to the quiche to reduce moisture and enhance flavor. Lean proteins such as diced chicken, turkey, or smoked salmon increase the protein content, making the dish more filling and suitable for a low-carb diet.

Seasonings like garlic, black pepper, paprika, and fresh herbs (parsley, chives, or thyme) enhance the overall taste. A small amount of almond flour, coconut flour, or crushed pork rinds can be used if making a crust, keeping it low-carb. This combination of protein, vegetables, and light dairy creates a balanced, flavorful quiche that’s satisfying and nutrient-dense.

Ingredients

6 large eggs
1/2 cup Greek yogurt or cottage cheese
1/2 cup shredded cheese (cheddar, mozzarella, or dairy-free option)
1/2 cup cooked lean protein (chicken, turkey, or smoked salmon)
1/2 cup fresh spinach, chopped
1/4 cup bell peppers, diced
1/4 cup mushrooms, sliced
1/4 cup onion, finely diced
1 teaspoon garlic powder
1/4 teaspoon black pepper
1/4 teaspoon paprika
1 tablespoon fresh parsley or chives, chopped
1 tablespoon olive oil or cooking spray
Optional: 2 tablespoons almond flour or coconut flour for a low-carb crust

Step-by-Step Instructions

Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or oven-safe skillet with olive oil or cooking spray. If using a low-carb crust, sprinkle almond or coconut flour evenly across the bottom and press lightly.

In a large mixing bowl, whisk together eggs, Greek yogurt or cottage cheese, garlic powder, black pepper, and paprika until smooth. This mixture forms the custard base for the quiche, providing a creamy, high-protein texture.

Sauté onions, mushrooms, and bell peppers in a skillet with olive oil for 3–4 minutes until soft and slightly caramelized. Add spinach and cook for an additional 1–2 minutes until wilted. Remove from heat and let cool slightly.

Layer the sautéed vegetables and cooked protein evenly in the prepared dish. Pour the egg mixture over the top, ensuring the ingredients are evenly covered. Sprinkle shredded cheese over the quiche for added flavor and a golden top.

Bake in the preheated oven for 25–30 minutes, or until the quiche is set in the center and lightly golden on top. Test doneness by inserting a knife into the center; it should come out clean. Avoid overbaking to maintain a tender, moist texture.

Allow the quiche to cool for 5–10 minutes before slicing. This resting period helps the quiche hold its shape and makes serving easier. Serve warm or at room temperature. Leftovers can be stored in an airtight container in the refrigerator for up to four days and reheated in the oven or microwave.

Tips, Variations & Substitutions

For extra flavor, add herbs like thyme, basil, or dill to the egg mixture. Vegetables can be swapped with zucchini, broccoli, or roasted cherry tomatoes. Protein options include tofu for a vegetarian version or turkey bacon for additional flavor.

If making a low-carb crust, almond flour, coconut flour, or crushed pork rinds can be used. A crustless quiche is also delicious and naturally lower in carbs. Cheese can be substituted with a dairy-free or plant-based option to accommodate dietary preferences.

Avoid adding excess moisture from vegetables; sautéing or roasting helps prevent a soggy quiche. Seasoning the protein and vegetables before adding them to the egg mixture enhances flavor throughout the dish.
